Ready-to-use ELISA kits are available for the detection of Cyclophilin A, an alias of the protein, peptidylprolyl isomerase A. The official gene symbol is PPIA. The kits can detect several species variants of the protein, including: human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian. The protein, with a mass of 18 kDa and length of 165 residues, is reported to be cytoplasmic and secreted. It is a member of the Cyclophilin-type PPIase family, PPIase A subfamily and may be known by other names, including: rotamase A, peptidylprolyl isomerase A (cyclophilin A), cyclosporin A-binding protein, T cell cyclophilin, PPIase A, and peptidyl-prolyl cis-trans isomerase A, and CYPH.
